摘　　要：根据鲁中软岩矿区开采引起地面下沉及地面井塔楼等建筑物倾斜变形的工程实际,采用非确定性研究方法,将深埋破碎金属矿体开采引起地面沉陷或岩体移动变形这一客观现象视为-随机事件,建立了开采引起地面沉陷或岩体移动变形分析的数学模型。利用该模型可对开采引起地面沉陷及其对地表工业建筑物影响进行具体分析评价。通过具体计算分析结果表明,在软岩地层条件下矿体开采地表移动变形的影响范围有随着采深的增加而逐渐增大的趋势。Based on results of the statistical analysis of a large amount of measured data in mining engineering, the fundamental theoretical model of ground surface movements due to underground mining is established by using the theory of probability. The formulas of rock mass displacements and deformations are developed and applied to the prediction of the ground surface movements due to underground mining. The agreement of the theoretical results with the field measurements shows that our model is satisfactory and the formulae obtained are valid and thus can be effectively used for analyzing and predicting the ground surface movements due to underground mining in soft rock mining areas. The results have shown that the area of rock mass displacements and deformations in overlying strata will extend with the increase in depth.
